All,

I'm building a large government extranet in dnn 6 and was looking for some thoughts and feedback, as we seem to have ventured into uncharted territory based on the discussions I've had with a few module developers.

The site has over 70,00 users and 100,00 security roles configured across a few dozen security groups, synced to AD. Each user is typically in no more then 10 roles.

Ideally i would have liked to avoid this number of roles, but we were forced down that path by the number of teams within the organisation ( over 2000) and the number of roles within each team ( typically about 25-30 per team) each role is unique to that location so you end up with the number of roles times the number of locations by security groups. Additionally users may be in one or many roles across one or many locations so we couldn't add these details as a profile property effectively. Further to this the people in each role change regularly, and there are usually several people in each role at each location.

As you would expect with the number of security roles we have run into some issues with some modules not being able to handle it and needing modifications done. Whilst the core itself has held up fairly well there are a few things that i was hoping someone may be able to give useful advice on.

1) the site is running quite slowly, which I'm assuming has something to do with the number of users. Can anyone suggest any configuration changes/tweaks/improvements that would help speed this up?

2) clicking on the show all roles security group does bad things to the site. Is there a way to disable this?

3) any other suggestions or tips you have relevant to configuring such a large DNN site would be most welcome.

Cheers.

wow,thats pretty impressive, nice to know DotNetNuke can hold up under that load.

As for optimising, I'd suggest running a sql profiler to determine what query(s) are causing the site to operate slowly - in some cases this will highlight additional indexes that may help with speed (we have to base our default configuration on "typical" sites so the best indexes for a site with a handful of roles may differ from one with many thousands) - http://msdn.microsoft.com/en-us/libra... covers much of this.

There is no way to disable the all roles group beyond editing the core directly.

Please note, the core has the concept of "role groups" - these are simply containers for other roles and can help when doing administration/working with page/module settings - I don't believe the AD provider has any concept of these but I believe you could add them yourself and update lists of your roles to be in particular role groups without impacting the AD sync (typically I'd recommend using the API for this type of thing, but in this case maybe a database update query would be best - backup first)

Finally, you can find a few performance suggestions at http://www.dotnetnuke.com/Resources/W... that may help.
